Megasquirt MS2 owner request

Postby Lokiel » Fri Apr 21, 2017 10:51 am

I've just published my paid Android Megasquirt MSTrackIt App and free MSTrackIt_Demo App on the Google PlayStore.

I've tested them on an MS3 and they SHOULD run on an MS2 but I haven't tested them yet on an MS2 so would like to know if it's possible.
The App doesn't support Bluetooth yet (waiting on a Bluetooth Serial dongle from DIY Autotune) but does support the USB and serial interfaces (FTDI USB-Serial cable/adapter is required for the serial interface; USB OTG cable/adapter is required if the Android device has a USB2.0 jack).

Would someone who has a MegaSquirt MS2 mind testing the free MSTrackIt_Demo App for me and let me know if it does run on an MS2?

The only difference between the paid and free Apps is that when the ECU is connected, gauges are only updated at 5 second intervals and the data is logged at 100x the specified rate.

The Android Apps can be found on the Google PlayStore (https://play.google.com/store/apps/details?id=com.lokiel.mstrackit and https://play.google.com/store/apps/details?id=com.lokiel.mstrackit_demo).

A QuickStart Guide and comprehensive User's Guide can be found at http://lokiel.weebly.com/android-mstrackit-app.html.

Thanks.

Read the Quick-Start Guide to get going as fast as possible - most of the User's Guide should be intuitive to anyone who's installed+used an Android App before.

If anything is unclear, please don't hesitate to comment and suggest improvements - developers tend to be crap at documentation and writing good User Guides.

Also, if it does work on the MS2 and you do decide to purchase the paid App, let me know and I'll refund you the A$6 purchase price.

So far I've found 2 MS2 issues, one I can deal with and another I'm not sure about and need some input from MS gurus (will post on Megasquirt thread too).

StanTheMan's mainController.ini file had the "signature" variable (used to verify that the firmware file is the same as that used by the ECU) defined in the "[TunerStudio]" section rather than the "[MegaTune]" section like the MS3 file does. The latest MS2 firmware has it defined in the "[MegaTune]" section so it's obviously been moved in later releases.

I can handle this easily by looking for "signature" in both sections.

The next problem I found was that the MS2's mainController.ini file doesn't define a speed value.
How is speed retrieved from the MS2?
Is it calculated from multiple MS2 values and if so, which ones?

MS3's are easy, the "vss1_ms_1" is Vehicle Speed Sensor 1 in metres per second.

Just did a search on http://www.msextra.com for this.

jsmcortina's response helped clarify this http://www.msextra.com/forums/viewtopic.php?f=101&t=61148:

"There is no speed-sensor function in MS2. You need MS3 for that.
Analogue inputs can be datalogged. See section 4.10 in the Setting Up Manual http://www.msextra.com/doc/pdf/html/Megasquirt2_Setting_Up-3.4.pdf/Megasquirt2_Setting_Up-3.4-82.html "


Now I love my MS3 even more!

For now I'm just going to make it MS3 only - sorry MS2 guys and thanks for your help Stefan.

Woke up at 3:00am and thought:

"Why not just use the Android device's GPS as the only speed source for the MS2?"

- couldn't get back to sleep, I'm a chronic insomniac and this was keeping me awake, so trying it now...

With great thanks to StanTheMan for doing all the MS2 testing, it looks like I can make the App work using the Android Device's GPS for speed.

I ended up making a new App, MSTrackIt_MS2 since that was easier than dealing with making unavailable MS2 options in the Android menus unavailable.

The MS2 does not define gear information nor gear ratios and final drive ratios so for the initial version I deleted this functionality.
I have the formula for calculation of the current gear number so can re-introduce this once I've added an interface to define the vehicle's wheel diameter, gear ratios and final drive ratio.

Once again. many thanks to thanks to StanTheMan.
